I think live is preferable for other reasons too. First off it's a
good idea for consistency with similar properties. Second, code like
the following would be very inefficient otherwise:

for (i = 0; i < el.attributes.length; i++) {
  if (el.attributes[i].name == "foo" ||
      el.attributes[i].name == "bar")
